I'll keep an eye out and try to help as much as I can!

Here's a tip to cover that situation. When you draw guidelines parallel to an edge that are supposed to lay "on face" start your guideline on the edge, move the cursor up/down a bit on the edge and then pull towards the direction you want. Nothing new here. But, instead of leaving the cursor on face where you want the line to be, move the cursor to some alternate perpendicular (or so) edge on the same face. This forces the guide line to stay on face. At that point you can enter the offset distance in the VCB or move along that edge to the desired offset location. To test if 2 perpendicular (or crossing non parallel) guidelines are actually intersecting, place the cursor on one GL and move it to the intersection. You should see a little red X. That indicates GL intersection. If all you see is a colored dot, the lines do not intersect. The dot means the point at the cursor lines up axially with both GL's. This works with GL's and edges as well.

cheers guys

No worries. Sometimes it's easy to get stuck because you are thinking about how to subtract geometry rather than to not make it in the first place. Sometimes it's the other way around.

Thanks Alvis Really helpful info just need to study the plugins.

In case someone comes along and wonders why soften AND hide took care of it... The geometry had some coplanar edges which are what hiding got rid of. An option to hiding them would be to tick the box for "Soften coplanar" or better, simply delete those edges. [image: 263W_ss.png]

Thanks TIG for your help. Unfortunately the computer in question had a bit of a meltdown and had to be returned. Installed kerkythea on new system with no problems. Thanks again for response.

@unknownuser said: Seems Gaieus has made a complete tutorial about this sort of piece of architecture! @gaieus said: Actually I am planning to post a whole series of tuts for these antique pieces so in time, there may be more of them (and more elaborate than that thing showing only the pointed arch) Here's #1

Having fixed it try Model Info > Statistics > 'Purge unused...' As well as the 'Fix problems...' button... What are you doing when it 'crashes'? What is the manifestation of this 'crash' ?

Sorry for the delay thats great thanks Ill have a look at them Keith

And that's the best part of working for family that you love. I can demand all sorts of things and threaten to complain to his mother, LOL and the boy (man actually) is a gem of a person, so after a little/alot/huge amount of nagging he generally comes through. Love what I do though!! Summer is the quiet time in the corporate event business, so I shall use any free time wisely to hone my Sketchup skills, such as they be. Fortunately again most clients, and probably to include yours with the TV, just want to get an idea of what the finished product is going to look like. It always amazes me how many people are not able to visualize and have to see it laid out in front of them, but then for the most part they are happy.

Now that you've got the hang of that try using the VCB twice. Place a guide line, then use the Move tool to make a second one (ctrl click move) type 1.5m enter, then 10x enter. This will place another 10 guide lines 1.5 metres apart. This works with most tools.

Hi Niclasbladh Can you post the photo?

@niclasbladh said: Perfect! Is the possible to render that setup in for example Maxwell Render? I do not know about Maxwell but it is generally possible to render a model image and layer it on top of the original photo IF the renderer's camera is perfectly matched with the SU camera. @unknownuser said: Any ideas where to find good quality HDRI's? There are lots of good resources - see this news article for instance: http://sketchucation.com/all-news/336-free-hdri-resource-at-hdri-hub Of course all depends on what environment you actually need.

Thanks for the reply and adjustments. I've got a lot to learn, but it seems trial and error is the best way. When I create an STL from your file, and from another project I was working on, I still get: i.e. 137 faces exported (number varies) 0 lines exported (all are showing 0) 400 objects ignored. (numbers vary) I guess my questions is- which of the 3 pieces of info is for information only, or are any of these 'error' messages I should be concerned with. (I don't have a 3D printer yet to try these out as far as printing compatibility.)

@jerrymich said: I understand now what you are saying about the components being unique. So, if I make a change to one of the unique components, it will NOT make it on the other unique ones as it normally does on a change to a component. Correct? Yes, essentially. I general, when you make a change to one instance of a component, all other instances get edited which is incredibly powerful when used correctly. Make unique breaks the relationship so the unique component(s) is no longer related to the others. This is also very useful in some cases. @jerrymich said: As a general guideline, is it better to make components as you go and then come back and group the components? Thanks for your help Jerry My approach is to make all the individual parts as components and do the nesting only after the individual parts/components are finished. I see too many incorrectly nest components in models by others. You have some good examples of that in this model. For example, take a look at your "board#18" That component is made of a component called "board#22 and a bunch of loose geometry that looks like a drawer case maybe. I don't use groups for anything. I only make components. Others do use groups but in about 10 years of using SketchUp for woodworking projects I've never found a case where a group makes more sense than a component. You can do as you choose, of course.

No trouble caused. Glad you got it worked out.
